LOCOMtlTIVE ASH-PAN.

To all whom it may concern:

Be it known that I, i l-roams P. Manners, a citizen of the UnitedStates, residing "at Ash-Pans, of .which the following is a full,

enable others skilled in the" art to which it appertains tp make and usethesame, referonce being bad tothe accompanying dravv ings, forming partof this specification, in Which--' Figure 1 is a side elevational Viewof a locomotive ash pan of my improved con struction, and showing thelower portions of the front and rear legs of the fire box in. section..Iiig. i2 is a plan view of my improved ash pan. 'l ig. 3is a rearelevational view of the ash pan. Fig. 4 is a sectional view taken apin'oxiirmtcly on the line 4-l of Fig. 1. Fig. a transverse section takenapproximately on the line 5--5 of Fig. 1. Fig. (3 is a detail sectionalview taken at the upper end of the ash pan, showing a water supplypipetherein, and one of the nipples attached to said pipe.

My invention relates to new and useful improvements in locomotive ashpans, the principal objects of my invention being, to construct acomparatively simple, strong and durable ash pan which will effectivelyprevent the dropping of live coals onto the right-ofavay, therebymeeting the requirements of the safety compliance laws; to construct anash pan, in such shape that it Will resist all tendency to buckle orbecome distorted as'a result of unequal expansion and contraction due tothe variation of the heat of the ashes deposited in said ash pan, andfurther to equip the ash pan with means in the form of a series of jetnozzles adapted to deliver water into the ash pan for the purpose ofquenching; the tire of all live coals within the ash pan and flushing.all ashes from said pan whenever desired.

A further object of my invention is to provide air inlet openings in thesides of the pan, which openings admit the air necessary to supportcombustion of the fire on ing. drawings, 10- designates the dependingSpecification of Letters Patent.

leg portions of the locoucitive boiler, and fixed thereto in the usualmanner is an, ordinarymud ring 11. Fixed to and dcpehding from this mudrinp he bodylZ one being constructed of United, and in the form of achute which gradually becomes narrower and deeper from one end to theother. The forward and highest and of the body of the pan is formed on agradual curve; for instance, on' a curve having a thirty-two inchradius, and from this point the body of the pan gradually becomes deeperand narrower so that the extreme rear end has a comparatively smallradius; for instance, a radius of approximatelyseventeen inches. Theside portions of the body curve gradually upward and outward to meet theside portions of the mud ring, 11, and formed in the upper portions ofthe sides of the body '12 immediately below thisnnud ring are openingslii around which are arranged outwardly projecting housings 14. Theupper ends of these housings 14 are opened, as designated by, 15, inorder to permit air to enter the upper portion of; the ash pan, andwhich air passes from thence upward through the grate in the locomotivefire box.

By my improved construction the body of the pan is in the form of atapered chute which declines from one. end to the other, and for thisreason all ashes and matter falling in the ash pan will, by gravity,tend to pass to the lowerlend of said pan. The upper portion of one endof the pan is closed by a fixed plate 1'6, and the lower portion of'this end is normally closed by a hinged door 17. This door is operatedby means of suitable mechanism such as toggle links 18 actuated by alever 19 which extends to the locomotive cab, and thus said door can belocked. in its closed position and opened from the cab whenever desired.

The wide end of the pan is closed by a plate 20, the upper portion ofwhich is fixed to the corresponding portion of the mud ring 11. end ofthe pan is a tubular header 21 which preferably follows the curvature ofthe adjacent portion of the pan, and fitted into said header is a seriesof short nipples 22 which project downward toward the inclined curvedbottom. of the pa.n. The ends of these nipples are-out off at an anglesothat'the jets of water issuing from said nipples will be deflecteddownward o; m th Positioned in the wide, shallow" a e nd locked in suchposition by the toggle links 1 3; Allashes from the fire box will drop 7into thei'as'h pan, and by reason of the in clinationof its bottomportion, saidashes 'willtend to gravitate toward the lower end of said;pan. Thus the ashes are. retained 'with'm' the ash pan and live coalsare prelvenited'ifrom, dropping onto the right-ofway;

desired the valve :24 can-be opened to permit water to pass into theheader 21 and issue therefrom in jet form through the nipples 22, whichjets pass downward over the bottom of the ash pan, flushing out theashes therein and killing or quenching any live coals in said ashes. Thedoor 17 is opened by manipulating the lever 19 from the cab,'and as thewater continues to issue 'in jets from the header, the entire contentsof the ash pan is flushed out through the open lower end.

My improved ashpancan be varied slightly in shape and construction so asto be utilized in connection with different styles of locomotives.

. 'It will be noted that the body of the im proved ash pan is curved-incross section throughout its entire length, and by such construction I-materially stiffen the pan against any tendenciesto warp or becomedistorted and out of shape by reason of un equal expansion orcontraction due to varying degrees of temperature within the pan.

The main body of the pan may be either formed of sheet metal or cast,and it may be formed in a single piece or made in sections.

It will be readily understood'that minor changes inthe size, form andconstruction of the various parts of my improved ash pan can be made andsubstituted for those,

herein shown and described without departing from thespirit of myinvention, the scope of which'is set forth in theappended claims.

I claim 1. The combination with a locomotive fire Ybox, of an ash panarranged beneath said fire box, the mainbody portion of which ash pan isconstructed from a single plece of material in the form of an elongatedchute, which is curved in cross section, and the bottom of which pan isinclined lengthwise, there being air inlet openings formed in the upperedges of said ash pan, a trans- 1.1 oases jet no zzles projectlng fromsaid pipe downwardly onto the inclined bottom (if the pan, the lowerends of which jet nozzles are cut off at an angle so that the waterissuing from said jet nozzles is delivered directly dowIl- Wardly at anangle onto the surface of the bottom of said pan.

2. Thecombination witha locomoti box, of an ash pan arranged bone tirebox, the main body portion of ash pan is constructed from a single pieceof material intlie form of a chute which gradually becomes narrower anddeeper toward one end there being air inlet openings formed in the upperportions of the side walls of said ash pan, a fixed wall closing theupper portion of the narrow deep end of the pan, a door arranged beneathsaid fixed wall for normally closin the lower poytion of the narrow deepen of the pan,.and means for delivering water on the wide and shallowend of said pan.

3. The combination witha locomotive fire box, of an ash pan arrangedbeneath said fire box, the main body portion of which ash pan isconstructed from a single piece of material in the form of a chutewhich-gradually becomes narrower and deeper toward one end there beingair inlet openings formed-in the upper portions ofIthe side walls ofsaid ash pan, a fixed wall closing the upper portion of the narrow deepend -.of the pan, a door arranged beneath said fixed wall for normallyclosing the lower portion of the narrow deep end of the pan, atransversely disposed water supply pipe arranged in the wide shallow endof the pan, and a series of jet tubes projecting from said water supplypipe downwardly onto the bottom of said ash pan.

4. The combination with a locomotive fire box, of an ash pan arrangedbeneath said fire box, the main body portion of which pan comprises asingle piece of material, the central portion of which is in the form ofa chute, which gradually becomes narrower and deeper toward one end, theside walls between the central portion and the sides of the fire boxbeing curved upwardly and outwardly, portions of the upper edges of saidside walls being cut away to form air inlet openings and housings fixedto the sides of the pan around said openings.
